* SCRUIBBING NOZZLE.

Application filed March 8, 1919. Serial Il'o. 281,430.

To a ll whom it may concern:

Be it known that I, WALTER L. LAMPKIN,

a citizen of the United States, residing at lid Kansas (lit in the county of Jackson and State of issouri, have invented a certain new and useful Improvement in Scrubbing- Nozzles, of which the following is a speci cation. J

My invention relates to scrubbin nozzles.

One 0 the objects of my invention is to provide a scrubbing nozzle arranged to be attached to a hose and adapted for various cleaning purposes, particularly the cleaning of automobiles. A further object of my lnventlon is to provide a novel scrubbing nozzle which is simple in construction, cheap to manufacture, not liable to get out of OIClGI WhlCh is durable, and which is efficient for the purpose of scraping and washing off dirt without injury to the Washed surface.

@till another object of my invention is the provision of a novel. shag adapted for use in connection with my improved nozzle.

The novel features of my invention are hereinafter fully described and claimed.

ln the accompanying drawing,

Figure l is a bottom view, partly broken away, of my improved nozzle shown at tached to a hose.

Fig. 2 is a longitudinal section on the line 2-2 of Fig. l, the hose being omitted.

Fig. 3 is a cross section on the line 3-3 of Fig. 1.

Fig. 4L is a perspective view of my improved nozzle provided with a shag attached thereto.

Fig. 5 is a perspective view of my improved shag or mop.

Fig. 6 is a perspective view of the shag or mop shown in Fig. 5 shown mounted on my improved nozzle.

Fig. 7 is a central vertical sectional view of the nozzle and shag shown in Fig. 6.

Similar reference characters designate similar parts in the different views.

l designates a tubular handle which has attached to it at one end a hollow nozzle head 2 provided with a circular peripheral flange 3 which is releasably embraced by a flexible cap l preferably of softrubber, provided with perforations 5, which are improvements in disposed. out of register with perforations I 7 of a baflie plate 6 mounted transversely in the head 2 above the cap 4:.

9 designates an internally screw-threaded coupling member rotatably mounted on the tubular handle 1, and which is adapted to engage in the usual manner the discharge end of a hose 11.

For holding the baffle plate 6 releasably in the head 2, the bafile plate is provided Patented Mar. 23,, 1920.

With one or more peripheral notches 10,

adapted to respectively receive one or more inwardly extending lugs 8 on the inner wall of the head 2.

In mounting the bafile plate 6 in the head 2, the baffle plate is slipped into its seat with the notches 10 registering with the lugs 8, and then revolved, so as to bring the baflle plate under the lugs with the notches 10- out of register therewith, as shown in Fig. l.

The under surface of the cap 4: is prefer-- ably, roughened to enable it to more readily scrape dirt from the surface which is being cleaned. Such roughening may be effects by providing one or more annular grooves 10 in the under side of the cap l, the said grooves communicating with the perforations 5.

In Fig. 4:, I have shown attached to the head 2 a mop comprising flexible material 12, such as canvas, provided with a puckering string 13 which is adapted to be drawn tightly and tied around the upper side of the head 2. To the periphery of the canvas 12 is attached an annular shag 14, which extends below the cap 4..

In the operation of my invention, water from the hose 11 passes through the tubular handle 1, the head 2, the perforations 7 in the baffle plate 6, and the perforations 5 in the cap 4-. The nozzle may be used for the purpose of preliminarily scraping dirt from the surface to be cleaned without employing the mop shown in Fig. 4:. The rough ened under surface of the cap l is scraped back and forth over the surface to be cleaned, and the water passing through the cap carries away the dirt. To clean ofi dust and light dirt, the mop shown in Fig. l may be advantageously used by being attached to the head 2 as shown in Fig. 4.

In Figs. 5, 6 and Z, I have illustrated a preferred form of mop consisting of a shag 15, which is held clamped between two transversely divided rings 16 and 17, the latter ring or band being provided with inwardly extending tongues 18, preferably sharp and integral with the band or ring 17, and which strands of the latter in place.

enter the shag 15 to more Securely hold the One end of the ring or band 19 is pro.- vided with one or more hooks 19 which are ada ted,to respectively enter either set of pe orations 29 provided in the band 17 adjacent to its-opposite end. Rivets 21 extend through the rin or bands 16 andl'l the shag 15 for olding these parts toget er.

, The ring or band 16 -is adapted to embrace the periphe of the cap 4 and to be locked in position t ereon by causin the hooks 19 to enter one-of the sets of per orations 20.

To hold the mop from vertical movement .on the ca 4, any suitable means may be provided. fn the drawing, Fig.. 5,; I have shown the upper and lower edges of the ring or band 16 provided withtwo annular rows of inwardly extending tgngues or projections v .22, said two rows of projections respect vely engaging the upper and lower sides of the cap 4. A

he operation of the form of m invention shown in Fig. 6 is the same as as been describedwith reference to the form shown in Fig. 4. The

' It prevents t e water .ressure from forcing I do not limit my invention to the structure shown and described, as modifications,

, within the scope of the appended claims, may be made without departing from the spirit of my inventions What I claim is 1. Ascrubbing nozzle comprisin ahollow head having an enlarged open en provided when the bailie late 6 effects a double functi0n.

- throu h said at its inner side with an inwardly extending lu a perforate baflle plate circumferentia y revoluble in said head and provided with a peripheral notch for receiv' therethrough said lug to permit the insertion and removal of the baflle plate, the In extending inwardl at the outer side of sai baflie plate for hol the latter in operative posltion gafile 'late has been turned to a position inwhic the lug is out of register with said notch, 21. perforate flexible cap removably fitted on and covering said open end and a tubular handle dischar into sai head and having means for a ac fiment to a hose.

2. A scrubbing nozzle having a hollow head provided with an open end, a perforate cap covering said open end, and a mop comrising two transversely divided ring memrs, one encircling the other, the inner ring member having atits upper and lower edges inwardly extending pro ections adapted to respectively en the upperiand lower sides of said cap, t e outer ring member havin means for releasably locking together its en s, and a shag held between said ring members and encircling said cap.

3. Ina scrubbing nozzle, a erforate soft rubber cap provided on its with grooves communicating with the perforations, and means for discharging water erforations.

4. n a scrw bin nozzle, a perforate cap having on its disc rge side grooves communicating with the perforations, and means for dischargingwater through said perforations.

"-5. In a scrubbing nozzle, a perforate flexible cap provided on its discharge side with an annular groove communicating with some of said perforations, and means for discharging water through said perforations.

In testimony whereof I have signed my name to this specification.

WALTER L. LAMPKIN.
